Question

There’s some code in our project that looks a bit like this:

Private Sub Method1()     Call InnerMethod End Sub  Private Sub Method2()     InnerMethod End Sub  Private Sub InnerMethod()     '' stuff End Sub 

What’s the advantage of doing Method1 over Method2?

Answer 1

From the MSDN:

You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function’s return value is discarded.

For example:

Sub Proc1()     Debug.Print 'Hello World' End Sub  Sub Proc2(text As String)     Debug.Print 'Hello ' & text End Sub 

In the immediate window, if you enter

Proc1 

then ‘Hello World’ prints. If you enter

Call Proc1 

then ‘Hello World’ prints. If you enter

Proc2 'World' 

then ‘Hello World’ prints. If you enter

Call Proc2 'World'  

you get a compile error. You would have to enter

Call Proc2('World')
